Arduino Tally Lights
vMix supports the use of custom built Tally Lights through use of the open source Arduino hardware platform. (See http://www.arduino.cc/)
vMix required that the StandardFirmata firmware be loaded on to the Arduino device.
To connect to the Arduino device, go to the Input properties (click the i button) and from the Tally Light tab, select the COM port of the Arduino device and select the Tally Number.
The Tally Numbers are assigned to individual Digital Pins on the Arduino in the order specified in the Tally Lights tab in Settings.
